The ViewModel/MVVM pattern continues to gain popularity, with a blog post showing up every so often, and with tweets and retweets popping up even more often :-). At the same time, there are some interesting topics beyond the core pattern that continue to fuel experimentation. A big one amongst those is how should applications use dialogs when using the view model pattern.

The crux of the problem is the desire to keep the view model independent of UI concerns, and ensure it can be tested in a standalone manner, but that often comes to odds when you want the view model to launch a dialog, and/or do some work after the dialog is closed.

While the Visual StudioÃÂ® Build menu's Build Solution option is the usual way developers compile their current work on a project, the process of building the complete solution for testing, deployment, or production often requires many more steps.

Underlying the My namespace's APIs is a fully extensible architecture you can leverage to customize the behavior of My and to add new services to its hierarchy to adapt to specific application needs. the My namespace is optimized to provide simple solutions to common problems. But if your requirements are different, you can use the My namespace's customization model to modify the behavior of individual My namespace members to meet specific application requirements.

Even when developers have recurring computer-readable metadata to process and a clear idea of how code should be structured, they can still find themselves in need of a technique to automatically generate the code to avoid the drudge work of repeatedly writing and tweaking it. Generative programming is a technique that addresses this problem. Using generative programming techniques, you can solve software engineering problems in families, rather than individually, saving time and coding effort. This article describes these techniques, and builds a sample template-driven code generator. The article also lists existing utilities that have been built with generative programming techniques, as well as actual code generators.

I have a MOSs environment that I have published through ISA Server 2006 and i am getting really strange behavior whentrying to interact with WorkLFow generated tasks when I have connected through ISA. This also seems to affect InfoPath Forms Services. I was wondering if anyone out there is seeing any problems when using ISA Server to interact wih Forms or WorkFlows?

ÃÂ

The error I get simply states:

the form cannot be submitted to the web server either because your computer is offline or because the host server is currently unavailable.

I upload a powerpoint file and convert it to wmv format.Since the process of conversion is huge process(depends on the size of the file.Usually around 5 to 10 minutes.)i want to do in the background.So i upload a file and copy it to the server.(i using mysql as the database).In the server i just want to do the conversion.Once the conversion is finished.it should update the table.The user can use the file some time later or the next time.How could i do this ? Could somebody help me ?

I am new to SSIS and am developing a package which takes input from an XML file and then populates an existing SQL table with these records. However, this is a very large XML file. I keep getting an Out of Memory exception. (This file is
210 MB)! So what I tried doing was separating this XML file into 8 smaller files.
Now, I can successfully load data from these smaller files one at a time. But how can I do all of them in the same package? I connected two XML tasks to the Data Flow task and get the error below. I also increased my timeout and number
of errors to no avail. Advice?
Error: 0xC002F304 at XML Task 1, XML Task: An error occurred with the following error message: "Exception of type 'System.OutOfMemoryException' was thrown.".

HI All,
I need a CAML query which will retrieve all the workflow tasks from all the site collections in a web application, which are assigned to the current logged in user and whose status is NOT STARTED.
I.e., ASSIGNED TO = CurrentLoggedInUser
STATUS=”Not Started”
Workflow Name is not null
Can any one of you help me regarding this Issue.
Regards,
Kumar.

A lot of Intranet users are challenged to keep track of tasks across multiple team sites.
Anyone find a technique that works?
It seems like it would make sense to live in a user's My Site on SP2010. Anyone doing it that way?

I have a simple SharePoint Designer workflow that starts when a new list item is created. The task owner is defined by a 'user/group' field selected from a sharepoint list. Of 150+ users, only 4 are not able to see the tasks when assigned.
I have the task list set so they only see their own. These 4 users do not see any tasks, where as everyone else does see only their own tasks. To test, I changed the list settings to show all. The users saw all tasks, but are not able to
edit the tasks assigned to them.
I feel the problem lies with how the workflow is assigning ownership of the task. When I use the sharepoint task list to manually create a task for these 4 users, they can see and edit them, but when the workflow creates the task - they can't.
Is there something special about how workflows assign task ownership based off Active Directory versus manually assigning tasks coming from the cached SharePoint profile? (As a test I deleted the user from the All People list of the site, and manually
added them back - no luck).Greg Appelt

I understand that you can have task lists created in SharePoint and have them display on a dashboard with something like % complete, etc.ÃÂ However, we have a client that has many different projects they manage that each have their own Microsoft Project file.ÃÂ They want to know when the milestones on the project are due and what the % complete is based off of the contents of the project file.ÃÂ Is there a way to pull this info from the project files and have it display in a dashboard or some other format?ÃÂ We don't want to have to manually enter the tasks in SharePoint - it should be automated. Thanks, Robert

We have few packages where we have enabled logging to msdb (sysssislog). And events selected are OnError, OnExecStatusChanged, OnPostExecute, OnPreExecute, OnTaskFailed, OnWarning.
When running this package from BIDS solution, all the event log to the table. However, when it is deployed and run as a job only some of the events get logged to msdb. The package however does run correctly and the data is loaded fine.
What we want is that every time a package runs, we should be able to see that each of the task has succeded or failed (like we used to in DTS)
Could anyone advise on what the issue seems to be?
